Specification of Letters Patent.

Application filed April 3, 1912. Serial No. 688,156.

T0 all whom it may concern Be it known that I, HENRY LANGER, a citizenof the United States, residing at Middletown, in the Vcounty ofMiddlesex and State of Connecticut, have invented certain new and usefulImprovements in Looms, of

Vwhich the following is a specification.

My invention relates to improvements in looms, and the object of myimprovement is to produce a loom that will operate to produce acorrugated tubular fabric, and one that is especially suitable for usein vehicle tires.

In the accompanying drawing -F igure l is a side elevation ofa reedsuitable for use with my invention. Fig. 2 shows in end elevationmechanism for providing upward and Vdownward movement tofmy reed. Fig. 3isa side elevation ofthe take up roll shown in Fig. 2. Fig. l is a sideelevation of a fabric made by my invention. Fig. 5 is i a side elevationof a modification of the .take up roll. Fig. 6 is a sectional viewfonthe line a' m of Fig. 2. Fig. 7 is a sectional view on the line y y ofFig. 3. Fig. 8 is a side elevation of the mechanism shown in Fig. 2 andother loom mechanism and the fabric. Fig. 9 is a front elevation of thesame. i

The reed A comprises a frame work supported so that the same can bemoved up and down to different positions and the samel is of thedierential type, being narrower at one end than at the other, beingprovided with the usual Vdents, arranged diverging downward as shown.The said reed is caused to move up and down in the lay Vof the loom inthe process of weaving and the width of the fabric will'be determined bythe particular position of the reed. When the narrow part of the reed isin position to beat against the weft the fabric will correspond in widthto the width of the particular portion of the reed, and similarly whenthe wider part of the reed is beating in the weft the fabric will becorrespondingly wide. The reedis caused to move upand down by suitablemechanism at the proper intervals corresponding to the corrugated effectdesired inthe fabric. The mechanism in Fig. 2 is applicable for onemethod of providing such movement vof the reed. In this mechanism A isthe reed which is suit` ably guided by propermechanism, B is a leverconnected to the reed A by a link 10 and pivotally supported by theother end.

A cam Sin contact with the lever B serves as the same is rotated toimpart the desired movement tothe reed A through the connectedmechanism, the falling movement beingelfecte'd by gravity. Movement oftheV cam S is provided by means of a set of sprocketA gears and chainfrom the cloth take up roll D. The cloth take-up roll D shown in Fig.` 3isrelatively large at the center and tapered toward the ends. Differentforms may be used for the cross-section o-f the middle of the roll, thepreferred form being of special design, more or less elliptical, anddetermined by the particular construction of the reed. The cam S has thesame general form as the cloth take up roll D of the special designmentioned has at the middle and the same form of cam is used eventhougha take up roll of modified form is used, such asDl.

As the reed is moved up and down to correspondto the different widthsdesired to produce the corrugated fabric it is evident that in order totake up the same length of warp at the center and at the edges provisionmust be made for a different amountof take up intermediate the edgesthanrat the edges themselves, which latter are curved and have longerlength than the center which is straight, and in order to do this andtoproduce corrugations that are equal all around I make use of a clothtake up roller D that is of peculiar shape, being essentially ellipticalat the middle portion and tapered toward the ends and merging into around cross-section.

The roller D shown in Fig. 3 Vis suitable for fabric having alternatelarge corrugations 11 and smallvcorrugations l2 and for this reason isprovided on one side with elliptical enlargement 13 and on the oppposite side with a smaller swelling or enlarged portion 14.
